Built a Folding Rig to test out NVIDIA Drivers to find the best for the GTX 6xx series Video Cards. No B-Stock GTX 780 as of yet.
I used my returned EVGA X79 FTW MB with an i7-3930K CPU OC to 4.0 GHz Corsair Vengeance Blue 16GB Memory CMZ16GX3M4A2133C11B
Same hardware that I had in my Old Rig but I am having issued with this MB like the PCIe Banks were turned off but one so I had issues with the two video card. Testing only on a GTX 660Ti (Fan Set to 70% NO OC) and using a GTX 650Ti for OS and Display use only. 
I seem to have a BSOD issue with Driver 326.80 so I stated as far back with NVIDIA Drivers as Shown Below.
I takes a while to pull stats as I am pulling them live at 5% 10% increments for an Average.
I will update the below code every 5%. My HFM.NET Status x660TiDriverTest Slot 00

So far it look like after install the DirectX Runtimes Driver 326.80 is now working, but I will wait till it completes a 100%.
 
No Go BSOD at 80% on ( 326.80) going back to Driver 310.90

FAH 7.3.6 using HFM.NET and set to pull every 3 minuets.
Driver 320.18 so far look the best but am also working the BSOD 116 problem as well.
Driver 326.80 & 320.49 Caused a BSOD 116, I have only ONE complete and that was while changing Drivers during a run.
Now I am hopping that I can complete one run on 320.18 after I installed the DirextX Runtimes then will give 326.80 a go.
 

"Make sure the PhysX is updating and down grading to match the driver" This and doing a clean install with each driver.
Removing EVGA Precision X as well between each Driver and clearing out the Registry as well.
My 760SC are Crunching so I cannot really test them out, I also may stop Crunching and only Fold.
Is it or is it not good to OC the GPU whiles Folding, Crunching I have read Not to OC the GPU.
If I recall you use 326.80 as well for Folding on your GPUs.

OCing is not something I normally do to my GPU's, when I do its only around 100/150Mhz.
I never push them to there max cost to much to replace. Yes I'm on 326:80, no BSOD while folding.

Thanks, for what ever reason only this Rig is BSOD with 326.80 but this is also the only Rig I have two deferent GTX GPUs.
All my other Rigs are using 326.80.

I had 2 bsod on the 326.80 today on W8. This is after folding and crunching fine for over 2 weeks. What OS is your test rig? I dual boot with W7 on a 2nd hdd and switched over and all is fine with drivers 320.49 there.

Forgot to ask are your 116 BSOD?

If you didn't know Folding GPU in Linux has become quite simple to setup now.
I have only tested Linux Mint 14 and Mint 15 <=15 being much easier to get up to date drivers for GPU.
Only thing is you would need to find out what CPU core count is a prime stable core count to use, such as 40x CPU core is one.
This is my plain with the 4x 12 core CPU as my G34 board only has 1 PCI-e slot for a GPU.
Need to find out what other core count below 48 is prime stable, really hate to drop 8 cores for 1 GPU.

Yes, I did have one rig setup to fold only on GPU at one time.
Dropping 8 Cores would suck, but for only one GPU to fold on is it worth the PPD.
I only dropped folding GPUs on Ubuntu 12.04 because I could not update the Video Driver and keep the OS stable.
I am still a Windows user at hart and I if could Fold BigAdv on Windows I would drop Ubuntu 12.04.
After 3 times installed Windows 7 back on this rig and Fold only on the GPU's. That Rig is now gone and was replaced with a X79 Classified MB with 3 GTX 760 of which I should have kept the 3 GTX 660Ti because they are about the same as the 760 and now that is my Crunching rig at least till the end of the year.
 

Thanks, I did download that tool with BOINC.
I can play with it and see what I come up with.

124 vCore to low, or lower your GPU to 1200.
What is your vCore set at now?
For me to keep the Temps down I do not OC my GPU and only OC to 4.0 on the CPU.

vcore = 1.34 fixed. Temps are great on air.
 
Wolf, the card seems solid, no need for rma.
 
Just for precaution, I lowered cpu to 4.0 although still in W7 and have had no problems there. When all wu's finish I'll carry those settings to W8.

I never push them to there max cost to much to replace. Yes I'm on 326:80, no BSOD while folding.

I'm the exact same way, I'm just a CPU overclocker, I leave my GPU's at out of the box settings, using 326.80 as well.
 
my GTX 770 gets between 90 - 100K on the P8900's.... though I don't use it for folding anymore as you know already lol

Every now an again I may enter a overclocking contest, then I will OC the snott out of my GPU's
but then the testing load is only for a few mins. at a time not 24/7 load like folding.

^^^ doesn't look like nvidia will ever fix the folding performance problem so 326.80 is still the best drivers to use.

I wish I could but am now getting 116 BSOD on my Test Rig, good thing that it is only on this Rig.
Would it be that Hard for NVIDIA to create a Custom Setting on their Drivers for FAHClient.exe and or FahCore_??.exe
It will take 15 hours @ 400 Watts on one GPU and the PPD is down to only 23533 PPD and only 1.532 WUs.

BSOD 116 is not good man, I had that on a GTX 570 before I sent it in for RMA, thats ussually a sign that the card is dieing.

Testing Driver 332.21 HFM At least I did Get a Core 17.
 
So far the Computer is not usable for other tasks.
I think that the Driver will crash sometime today, we will see.

It is now at 69% and the ETA is 05:01:44 Hours.
 
Based on this I would say the 332.21 Driver is a NO GO for Folding for the GK104 GPU.
 
And now FH and NVIDIA Must Not be working to correct the driver problem for some of the older GTX 6xx and 760 770 cards this tells me that FH is really only supporting the newer GK110 and higher GPUs or is it NVIDIA Not?
Maybe AMD may Fold Better the NVDIA for the Money, I do not care for AMD so then that would lend to stop folding on GPUs.
